[comp.text.tex] Wanted: Literature using METAFONT/TeX for bitmaps

img@eng.cam.ac.uk (Ian Green) (07/18/90)

I remember reading somewhere an article that described a means by
which a *binary* bitmap image could be manipulated by TeX as a
character (glyph?) I think it must have been a TUGboat or TeXhax, but
I can't find it. Any pointers?  (I'm not referring to halftoning etc)

Cheers, Ian Green
